description The invention discloses a method for identifying micromechanical behaviors among granular mixtures based on acoustic emission characteristics. The method comprises the following steps of placing granular mixture particles on a lower loading plate of a single-particle loading device, installing an acoustic emission measuring system, and controlling an upper loading plate of the single-particle loading device to crush the granular mixture particles; and acquiring an axial load applied to the granular mixture particles by the single-particle loading device in the whole loading process, acquiring an axial displacement generated when the granular mixture particles are compressed in the loading process, and acquiring an original acoustic emission time domain electric signal generated in the crushing process of the granular mixture particles in the whole process through the acoustic emission measuring system. The method is advantaged in that the micromechanical behaviors among the granular mixtures are identified ac
